TOWER CORNER CONSTRUCTION.

Application filed May 28, 1923'. Serial No. 642,009.

T 0 all whom it may concern-.-

Be it known that I, ROBERT FRANKLIN TIsRoN, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in Tower Corner Constructions; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in corner structures for towers such as the so called turnbuckle derricks. Towers of this type have vertical corner members built up of separate sections coupled together and connected by vertically spaced horizontal girts and by inclined brace rods, and it is the principal object of the present invention to provide an extremely simple, inexpensive and efficient device which serves as a coupling for the abutting ends of corner posts, and an anchor for the inclined brace rods, and as means for connecting the girts to the posts.

Another object of the invention is to provide novel means whereby the coupling device is held against downward sliding on the up er end of one post, while it is being secured to the latter, before placing the next post upon said first-mentioned post.

With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure 1 is a perspective View of a tower showing the use of my invention.

Fig. 2 is an enlarged perspective view of one of the couplings and associated parts.

In the drawings above briefly described, the numerals 1 designate a plurality of corner posts resting one upon another to provide four corner members rising from an appropriate base frame 2, to which they are anchored as indicated at 3. Vertically spaced girts 4 are provided to hold the corner members in correctly spaced relation and the usual turnbuckle brace rods 5 are employed to impart the necessary rigidity to the structure.

For coupling the abutting ends of the posts 1 together and for anchoring the girts 4 and the brace rods 5, I make use of a plurality of duplicate coupling members of the type disclosed most clearly in Fig. 2.

The numeral 6 designates a right angular metal plate adapted to contact with the outer sides of the meeting post ends, the two halves of said plate being suiiiciently wide to extend beyond the posts. These extended plate ends are formed with key-hole slots 7 in their corners, with the large ends of the slots disposed outwardly. A pair of right angular post clamping bolts 8 having nuts 9 on their ends, are provided to engage the inner sides of the posts, said nuts being insertible through the enlarged slot ends 7 without the necessity of removing said nuts. As these nuts are then tightened, the ends of the bolts 8 are drawn'iinto the relatively small inner ends of the slots 7, leaving the enlarged outer ends of said slots free for hooking the rods 5 to the plate 6, as indicated at 10.

Between the slots 7 the extended ends of the plate 6 are provided with bolt holes to receive bolts 11 or other fasteners by means of which the girts 41 may be fastened to said plate.

When constructing the tower, a plate 6 is clamped upon the upper end of a previously set post 1, before the next post is secured in place. Hence, it is desirable to provide means to hold the plate 6 against downward sliding while it is being initially clamped in place. For this purpose, I prefer to stamp one or more tongues 12 inwardly from the plate to rest upon the upper end of the previously set post. These tongues also hold the posts and plate against relative vertical movement when the brace rods are tightened.

By the use of my invention, a tower may be easily built up in sections, completing one section before the next is added and thus the constructing operation may be more easily and more safely performed than when following the usual methods of construction, most of which require that the sections of the corner members shall be secured together before erection. Another advantage is that in case any girt or brace rod should be broken, it may be easily replaced without the necessity of tearing down any parts of the tower.

As excellent results are obtainable from the details disclosed, they are preferably followed, but within the scope of the invention as claimed, minor changes may be made.

I claim:

1. A post coupling and brace anchor for towers, comprising an angular plate for ap plication to the outer sides of two abutting,

larged ends are disposed outwardly, and any gular post clamping bolts having nuts insertible through said enlarged slot ends, said bolts when tightened occupying the smaller ends of the slots leaving said enlarged ends open for hooking braces to the plates.

2. A structure as specified in claim 1; said plates having additional openings to receive girt anchoring fasteners.

33. A structure as specified in claim 1;

said plate "having at least'one inwardly exi tending tongue to rest on the lower post and hold the plate against downward sliding when clamping it initially in place.

In testimony whereof I have hereunto afiixed my signature. 1

ROBERT FRANKLIN TISRON.
